What are the types of isolation transformers?
Isolation transformers are used to provide electrical isolation between circuits, thereby providing safety and noise reduction in electrical systems. The main types include:
Single-phase isolation transformers: These are designed for use in single-phase AC circuits, providing isolation between the input and output sides to protect sensitive equipment from electrical noise and faults.
Three-Phase Isolation Transformers: Used in three-phase AC circuits, these transformers provide isolation and ensure balanced power distribution on three-phase systems. They are commonly used in industrial applications where three-phase power is required.
Autotransformers: A type of isolation transformer in which the primary and secondary windings are electrically connected but have different turns ratios. They provide some level of insulation and are often used in situations where a slight voltage adjustment is necessary.
What are isolation transformers?
Toroidal Isolation Transformers: These transformers use a toroidal (ring-shaped) core to provide insulation. They are known for their compact size and low electromagnetic interference (EMI) characteristics.
Isolation transformers are electrical devices designed to isolate a circuit from the power source to ensure safety, reduce electrical noise, and protect sensitive equipment. They operate using separate primary and secondary windings, magnetically coupled but electrically isolated from each other. This insulation helps prevent electrical faults from affecting connected equipment and reduces the risk of electric shock.
An isolation transformer is another term for an isolation transformer. It serves the same purpose of providing electrical separation between circuits to improve security and protect sensitive equipment. The term “isolator transformer” emphasizes the main function of insulation.
Transformers are classified into several types based on their application and construction. The main types include power transformers, distribution transformers, isolation transformers, instrument transformers (current and voltage transformers) and autotransformers. Each type plays a specific role in electrical systems, from adjusting voltage levels to measuring electrical parameters.
Current transformers, used to measure and monitor current, are of several types:
Bar-type current transformers: have a bar-shaped conductor as the primary winding.
Toroidal current transformers: have a ring-shaped core with the conductor passing through the center.
What is an isolator transformer?
Window type current transformers: include a window through which the conductor passes, with the secondary winding wrapped around the core.
Clamp Current Transformers: Designed to clip around a conductor for measurement without disconnecting the circuit.
